The external spore morphology of Phylloglossum drummondii was studied with the scanning electron microscope and shown to share a number of features with spores in the subgenus Urostachys in Lycopodium. Within Urostachys the affinities of P. drummondii were less evident: the foramino‐fossulate distal face, pyramidal proximal surface, and subcircular outline of its spores are similar to spores in the section Phlegmaria while the weakly foveolate proximal surface and raised laesurae are characteristic of spores in the section Selago.
